RV Calculated Loads

[starbright28]

We have a RV post mounted box. It contains a 50Amp receptacle and a 20A receptacle. How do you calculate the load to shown on a panelboard schedule for the 50Amp receptacle?

Thanks.

551.73 tells you to figure the pedestal at 9600va. It then gives you a table of demand factors to apply depending on the # of pedestals in the panel. These demand factors are minimum and sometimes underestimate the load present.
